Abstract

The invention discloses a Q235B hot-rolled steel plate enamel and a preparation method thereof, which comprises the following raw materials in weight percentage: porcelain powder: 60% to 75%, antiknock agent: 0.5% to 2%, pigment: 1 %~3%, sodium nitrite: 0.15%~0.35%, borax: 0.15%~0.4%, calcium carbonate: 0.1~0.5%, kaolin: 4%~5%, quartz powder: 3.6%~5.5%, urea: 0.5%~1.5%, water: 27%~45%. The present invention uses ordinary Q235B hot-rolled steel plate as the base material of enamel products, and the manufacturing cost is relatively low, which is more conducive to the popularization and use of enamel products; The surface has anti-corrosion ability, and the glaze body has stable properties, low cost and simple process.

Description

technical field [0001] The invention belongs to the technical field of steel plate enamel, and in particular relates to a Q235B hot-rolled steel plate enamel and a preparation method thereof. Background technique [0002] Steel enamel products have a wide range of applications. At present, the base material of enamel products on the market generally adopts enamel special steel plates with a carbon content of ≤0.08%. The enamel is ball milled and sprayed on the special enamel steel plates. After sintering in an enamel furnace, enamel is obtained. product. Enamel products need to use enamel special steel plates with low carbon content, and the manufacturing cost is relatively high. Contents of the invention [0003] In order to overcome the deficiencies of the above technologies, the present invention provides a Q235B hot-rolled steel plate enamel and a preparation method thereof. [0004] The technical solution that the present invention overcomes its technical problem ad...
